Subject: Re: [PATCH 0/4] Allwinner D1 video engine support

Hi Samuel,

What is the status of this series? It seems to be mostly OK, but I did see
a few comments suggesting improvements.

Does this series depend on your PPU work? That was not clear.

I do think there were enough small comments to warrant a v2, unless you disagree?

Regards,

	Hans
